Specification of Letters Patent.

BOTTLE.

Patented April 23, 1907.

Application filed July 30,1906. Serial No. 328,472.

To all lull/011? it may concern:

Be it known that we, CLAUDE B. DAVIS and ADAM T. 1 1N011, citizens of the United States, residing at Chase City, in the county of Mecklenburg, State of Virginia, have invented certain new and useful Improvements in Bottles; and we do hereby declare the following to be a full, clear, and exact description of the 111V611il011, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bottles and more particularly to those constructed to prevent refilling after being emptied, and has for its object to provide a bottle equipped with a valve arranged to prevent its refilling, and which will be extremely simple and cheap.

Other objects and advantages will be ap parent from the following description, and it is to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

In the drawings forming a portion of this specification and in which like numerals of reference designate similar parts in the several views, Figure 1 is a vertical section through a bottle neck having the present valve arrangement. Fig. 2 is a transverse section of the guard just above the valves. Fig. 3 is a vertical section of the guard. Fig. 4 is an elevation of the guard with the valve closed.

Referring now to the drawings, there is shown a bottle neck 5, having a cylindrical member 6 engaged therein, which is reduced adjacent to its ends, as shown at 7, to form upper and lower heads 8 and 9 and an intermediate portion 10 spaced therefrom. Diametrically opposite grooves S and 9 respec tively are formed in the periphery of the heads 8 and 9, and the grooves of the two heads aline longitudinally of the member. The central portion 10 has grooves 10 therein at opposite points, extending longitudinally of the member, and these grooves 10 are offset to bring them out of alinement with the grooves 8 and 9 and opposite the solid portions of the head which lie between the grooves. The upper portions of the side walls of the grooves 9 are slanted outwardly to form valve seats A, and located for movement into and out of each of these valve seats, there is a valve 11 having outer convex and inner concave surfaces B and C re spectively, the concave surfaces receiving the adjacent reduced portion 7 of the member thcrewii-hin. while the convex surfaces conform to the concavity of the bottle neck. Each of these valves has a downwardly extending stem 11 formed integral therewith, and lying with its groove 9 and these stems are of such a length that they permit of movement of the valves into engagement Willi the portion 10 without disengagement of the stems from the grooves 9, and thus these stems act as guides to insure correct seating of the valves.

As shown, the stems 11 are carried. by the inner portions of the valves 1 1, and it will be observed that the bottle when inverted is free for the passage of its contents therefrom because of the movement of the valves out of their seats, the valves passing again into their seats when the bottle is returned to its normal position.

A transverse passage 12 is formed within the portion 10 opening at one end into the periphery thereof, and slidably engaged in this passage, there is a retaining plunger 13 movable into and out of the passage and held normally projected therefrom by a spring 14 engaged between the plunger and the inner end of the passage. This plunger is thushcld against the bottle neck to prevent disengagement of the cylindrical member therefrom and, as shown, the bottle neck may be provided with a socket 15 for the reception of the plunger.

What is claimed is:

1. The combination with a bottle, of a member engaged. in the neck thereof and having spaced portions and a reduced connecting portion, said portions having offset passages formed thcretlnough, each passage of the lower portion having a valve seat at its upper end, a valve located between the por tions for movement into and out of each valve seat, each valve having a concave surface receiving the connecting portion of the member, and a stem carried by each valve and slidably engaged in the correspomling passage of the lo \ver port on.

2. The combination. with a bottle, of a member engaged in the neck thereof and having spaced portions and a reduced connecting portion, said portions having offset passages formed therethrough, each passage of the lower portion having a valve seat at its upper end, a valve located between the portions for movement into and out of each valve seat, each valve having a concave surassa e of the lower ortion and means for holding the member in the neck.

3. A valve mechanism for bottles comprising a cylindrical member having a reduced central portion and resultant spaced heads, each of said heads having oppositely disposed peripheral grooves opening through their ends, the grooves of the two heads bein offset from each other, the side Walls of the groove. of one head being diverged at their inner ends to form a valve seat for each of said grooves, a valve engaged in each valve seat and having a concave inner surface receiving the reduced portion of the member, and a convex outer surface arranged to lie flush and to correspond with the outer surface of the head, and a stem carried by each valve at the inner portion thereof and lying in the corresponding groove, said stems being arranged to permit of movement of the valves into engagement with'the other head without disengagement 'of the stems from their grooves.

4. The combination With a "bottle, of a member engaged in the neck thereof and including upper and lower heads, a central portion spaced therefrom and a reducedconnecting portion, said central portion and heads having ofi set passages formed therethrough, and upwardly opening valves for the passages of the lower head.

In testimony whereof, We affix our signatures, in presence of two witnesses.
